It is with great sadness that we learn of the death of Bob Crow, general secretary of the Railways, Maritime and Transport Union (RMT), at the age of 52. Our thoughts and condolences are with his family, friends and comrades at this difficult time.

Bob was a significant presence on the left and in the Trade Union movement, a champion of defending the jobs and safety of London Underground workers and a fighting trade unionist who was willing to push forward the interests of the working class, even when that meant he went through periods of intense personal attack.

We are thankful for his dedication to the fight and take heart that the militant workers of the RMT will continue a fitting legacy of struggle.
